Some session attributes lost

hi
traversing between different jsp pages,
I find that three of the session attributes are lost.
While it is set, I can print it and verify that it exists in the session.
Is there any limit on the #, or is it something else.
thanks in advance

Session (attribute) lost between JSPs

Hi All
I've seen many post about losing the session but all of them (the ones I've seen) are different.
Anyway, I have 3 jsp's, the first only submits a form like
<FORM METHOD=POST ACTION="SaveName.jsp">
What's your name? <INPUT TYPE=TEXT NAME=username SIZE=20>
<P><INPUT TYPE=SUBMIT>
</FORM>The second one stores the username in the session like
<%
   String name = request.getParameter( "username" );
   session.setAttribute( "theName", name );
%>
<HTML>
<BODY>
Your name is <%= session.getAttribute( "theName" ) %><br/>
<A HREF="NextPage.jsp">Continue</A>
....So far everything works fine!
Then, when I click on continue the third jsp is reached:
<HTML>
<BODY>
Hello, <%= session.getAttribute( "theName" ) %>
</BODY>
</HTML>This is only basics, but the last jsp shows 'null' instead of the name.
I'm runnint tomcat6 behind apache. The only thing added to the apache configuration was
ProxyPass /tomcat/ ajp://localhost:8010/Maybe I need to do more configuration ? Any suggestions ?

Hi,
This should never really happen when you bring up a Web Server or to what so called a loadbalancer in place as ultimately the container which creates the session Object.
I strongly feel that the Webserver(Apache,Sun App Server or IIS) is not passing on the jessionid cookie value which is actually responsible for this action when we are not using url writing for maintaining. .
How do test that ??
try the below code snippet and the rest all is understood on what values you get.
<%
   //Get the values of respective Properties
   boolean sessionIdFromCookie = request.isRequestedSessionIdFromCookie();
   boolean sessionIdFromUrl = request.isRequestedSessionIdFromURL();
%>
From Cookie : <%=sessionIdFromCookie%>
From URL : <%=sessionIdFromUrl%>Well to sort out problems as these you got to enable passing of jsessionid cookie to the Application Context via Webserver which might call for additional set of configurations from webserver end and AJP part.
Just as an example let us consider in the case employing IBM http server
http://publib.boulder.ibm.com/infocenter/wasinfo/v6r1/topic/com.ibm.websphere.base.doc/info/aes/ae/xjta_ihs_int.htmlor a neutral way to fix this issue is to adopt usage of a technique called URLREWRITING.
How do you do that ??
A quick google search provided me the below results

HELP: attributes saved in session got lost

Hi, All:
We have the following architecture:
Client IE Browser Verison 6.0. --> Gateway
--> Portal Server 6.0
--> Sun One Web Server 6.0
We have Portal server (http://portalURL) and Web Server (http://webserverURL) behind one Gateway (https://gatewayURL).
One application is deployed on Sun One Web Server.
After user login to Gateway/portal, user gets the default portal page https://gatewayURL/http://portalURL/defaultpage.jsp, the user then is redirected to A.jsp in Sun One Web Server https://gatewayURL/http://webserverURL/xyz/A.jsp.
A.jsp saves variables in the session using:
session.setAttribute("CLIENT_ID", "5" );
Right after that, the user access the B.jsp in the Sun One Web Server by
https://gatewayURL/http://webserverURL/xyz/B.jsp
B.jsp tries to retrieve the varialble stored by A.jsp using:
String clientId = (String)session.getAttribute("CLIENT_ID");
But it fails, the clientId is null.
What we find is that somehow a new HttpSession is created for every new request from same browser session, so A.jsp and B.jsp have different session.
We are losing all the session attributes saved in the previous requests.
however, there is no such problem with with Mozilla 1.7a - variables saved in session in A.jsp can be retrieved by B.jsp.
Thanks.

Hello ,

How to save the login ID as a session attribute ?

I am using form-based authentication in a web application which is being deployed on a JBoss 3.2.3 server. I am authenticating against an Oracle database by way of a DatabaseServerLoginModule (JAAS).
I would like to save the user's login ID as a session attribute in order to be able to use it later in the application.
It's not obvious how you can capture this information and add it to the session, since it seems that the login ID is lost once the authentication is done by j_security_check process.
Is there some way to tell the servlet container to save the login ID as a session attribute as part of the j_security_check process (something along the lines of "if the authentication succeeds add the login ID as an attribute to the session") ?
Is there another approach ? What is the accepted "best practice" for doing session initialization after authentication ? For example if a user needs to have several attributes set in their session after login -- how is this handled ? I have done this before with a login servlet which did both the authentication and the session initialization, but when using form-based authentication and j_security_check it's not clear to me how you go from the authentication to the initialization logic.
Thanks in advance for any suggestions or insight.

You should already have it... hidden in request.getUserPrincipal().getName()

Strange problem - session attribute

Hi,
This one is really strange. I have a search field on my form. When I enter a value in the field(say 'test data') and then click 'Submit', the search is performed. To retain the above search value on the screen, I put it into a session attribute and then pick it up again from there.
The problem is, when the screen reloads after the search, only the first part of the string i.e 'test' is displayed and data disappears. Is it that when get values of session attributes in a JSP, only the value till an empty space is considered?
I would be grateful if someone could let me know if they have ever experienced the same of if there is any documentation stating this. I am totally lost!
Thanks in advance.

Greetings,
Could you please include some of your code. It seems like somewhere along the process you are either losing or not storing all the data properly.
Thanks,

Javascript to JSP question...Can javascript function set session attributes

hello,
i have a web app that, on one of its pages, displays "tabbed pane" as an image map at the top (a la amazon.com). my problem is this: each "logical" page contains separate forms that all use the same javabean. in other words, imagine that the tabs represent an account maintenance web ui for an on-line record store. the first tab might be labeled "General," the second "Contact info," the third "Shipping Info." Each uses the same account bean and displays portions of its properties relevant to the tab at hand. what i want to do is allow a user to enter the account maintenance ui, update info on the first tab, click on tab two and have the request with the changes sent to a processing jsp. yet, since each "tab" is actually a separate URL to another page, how do i get the updated info on the first tabe without adding some sort of "SAVE" button on each tab. ive considered using javascript, but dont know how to get the request params out of the first tab whn i click on another tab. is it possible to include an "onClick" function in each URL that "grabs" the updated form fields off the preceeding tab? can a javacript function set session attributes in jsp?

hello there,
wow, you've created one big mammy-jammy tool.
first, javascript cannot access, set values to the session, without having to post to another JSP. javascript is great for manipulating objects, layers, form values, etc.
you have 2 issues [if i understand correctly]:
1) you need to able to save user info for a specific tab without having to reloading the page.
---you can create a form for EACH of your tabs and POST all the information to a hidden IFRAME or LAYER for NN4. that hidden IFRAME / LAYER will load a JSP page which with all the parameters you posted to it. or you can build a FRAMESET and target that document["frame-name"].src with that same JSP.
2) handling when the SAVE INFO action should happen: hence some javascript event handler: onMouseOver, onClick, etc
---i don't know the dynamics of your tabs, but if store which tab was clicked on last, then if the user clicks on some other tab, javascript can submit that FORM to a JSP [see condition above]
you have an interesting tool. can i see?
i hope i wasn't too confusing, but your problem is sooo interesting. =)

Problem removing session attributes

I have a problem removing session attributes
I try w/ mysession.removeAttribute("key");
but it still lives in memory. I've tried setAttribute("key", null) as the API states that will do the same thing, but it doesn't work.
I can get mysession.invalidate() to work, but I want to keep some of the attributes there, while removing another.
I get no exceptions and no errors.
Help.
Running Tomcat 4
jre 1.3.1

Actually,
response.addHeader("Expires", "-1");should be enough.
The browser should then contact the Web server for updates to that page via a conditional If-Modified-Since request. You don't want a cache disabling 'overkill', since you'd still want the page to remain in the disk cache and used in appropriate situations without contacting the remote Web server, such as when the BACK and FORWARD buttons are pressed...
Anyway, try this first, and if it doesn't solve your problem, add the other cache-disabling headers, as outlined in the previous post.
If you're using JSP, verify also that your page has
<%@ page session="true"%>

Setting session attributes at the Role level

I am running AM7.1 in Legacy mode and I am trying to create a role and assign session attributes at this role level. I followed the instructions for doing this but it does not seem to be working. I created the role and added the session service to it. I then went in an changed the attributes (Max Idle, Max Session, etc.) to the values I need for the role. I then assigned the role to a user. However when I log in as this user and look at the Active Sessions panel all of the values are still saying they are set at the defaults. It is not picking up the new values for the user. Am I missing something? Help! -Jeff

Reply i was also getting this problem in relam mode but 7.0..........but when i specify in the url?role=rolename..........i see the session info applied but i wanted it to be dyanmically applied(without specifiying the role in the url).......i have raised an SR but that is for 7.0 .........please do it for 7.1 i think you might get some response.

Session Attribute

Hi,
We have some problems with our portlet (deployed on portal 10g). We have two “applications”. One is outputting a menu with links to the other JSP that is redirecting the user.
In the first application we set a session variable that needs to be read in the other JSP. But the redirecting script can’t read the session variable (session.getAttribute always returns null).
And the funny thing is, we have an old version of these two scripts that are deployed and running on the same portal in the same OC4J (under different name) and they work properly.
We checked all the settings we could think off, but we didn’t find anything.
Regards,
Gregor

Hello Gregor,
Here i have few quick thought that hit my mind..
I am assuming you are developing JPDK portlet, right ?
Just check out two settings,
First:-
While registering the provider, on the General Properties page we first write the web provider URL. Then on the same page, under User/Session Information section, make sure that Login Frequency must be selected as Always and Required Portal user specific session information must be checked.
Click on Apply and OK.
Second:-
In the provider.xml the session attribute must be set to true.
If you have already done the above steps, and still facing issues.
please let me know, we will find some solution.
Thanks

Error in retrieving session attribute for ejb remote in clustered env

          We store EJB remote object in session and differnt clients retrieve it from sessionbefore
          making a business method call. This seems to work in most cases but sometimes
          it gives the exception attached. This happens only in a clustered environment.What
          has been observed is that if we put the remote object inside a hashtablewhich
          in-turn is stored in session retrieval from hashtable does not give thisproblem.
          Any suggestion / solution would be greatly appreciated.

Fetch a session attribute without transfer it as parameter

Hellow everyone, now I meet a greate problem:
I put a session attribute with a code (as identifier) in HttpServletRequest,
but do not know if there is any way to fetch it from request object in a none servlet/jsp class
without transfer the HttpServletRequest object? for example, should I use some context object fetch it
directly from context rather than from request object.

Hi!
If you want to fetch the session object without transfering the parameters, then you can try with the getAttributeNames() method of the HttpSession Interface.
Try it out!
If u face any problem mail me, here itself or else to my mail id : [email protected]

Jsf issue using session attributes

I have a JSF issue where I can't seem to get session attributes to be stored as initial values on my inputText field below. I've tried 2 things: (1) reading session attributes in my locrateForm bean, and then use getter method to get them to the jsp form ( I read the session attributes in the getter - I know it's a no-no, but I'm desparate)...
(2) reading session attributes in my jsp and storing them to the inputText fields.
Both times, I can successfully read the session attributes, but I can't get it stored in the inputText below....Pls provide this new jsf user some direction...thanks in advance...
Also....I thought the below EL would auto-invoke the getter method in the "locrateForm" Bean to get the initial value, but it's not...my books don't explain this well...
<h:inputText id="locrateDest" value="#{locrateForm.locrate.locrateDest}" >
</h:inputText>

Can you show us the snippit of your faces-config.xml for locrateForm and the snippit of the Java implementation that involves locrate and locrateDest?

Hi,

You can't get session attribute from Forms because it runs as an Applet in the browser and does not have access to the server side request object.
You can access request parameters that are used to call Forms, but that's it.
2.If I want the Menu always display on top and application display on botton of browser. HOW CAN I DO?
Use HTML frames
